SPECIFICATION forming part of Letters Patent No. 538,783, dated May 7, 1895.

Application filed January 19, 1895. Serial No. 535,460. (No model.)

L'b all whom t may concern: with the outer`shell shown in Fig. S. Fig. 10 Be it known that l, NVILLIAM F. HUTCHIN- is a cross-'section on the line 1Q 10 of Fig. 8.

The box is of a generally elliptical I5 My invention relates to improvements in shape to correspond with the usual form ot' boxes of this class; and the object of my'inbrush back, but obviously it may be of any vention is to produce a box which can be necessary shape. The box is closed at theboteasily arranged in a shaking or jolting matom, and has a removable cover 14, which can 7o chine, which has internal mechanism of a simbe fastenedin any suitable Way, but as the -zo ple character adapted to be applied to brush cover must be attached rmly and yet be backs o different sizes,'which `has anv abutquickly applied or removed, the fastening dement plate Abeneath the brush back holder, vice shown is desirable. which has a ysimple means of adjusting the The fastening devices are applied to oppo- 75 abutment plate in relation to the brush'back, site sides of the cover, and each has a stud and which is constructed in such a way as to 15 on the cover, on which is journaled an ecbe very durable and to Work without rattling. centric 16 having a handle 17 with a later- To these ends my invention consists of cerally protruding pin 18, which is adapted to tain features of construction and combina` engage the shoulders 19 on diametrically op- 8o tions of parts, which will be hereinafter `de' posite sides o the eccentric strap 20, this 3o scribed and claimed. strap being mounted on the eccentric 16 and Reference is to be had to the accompanying having secured to it a depending arm 21 With drawings, forminga part of this specification, a hook 22 at its free end, to engage a pin 23 in which similar figures of reference indicate on the side of the box. 85 corresponding parts in all the views.

In the lower portion 12 of the box is a ring o5 Fig. 5 is avsectional elevation ofA the locking 24, which is movable up and down and has device to fasten the cover on the box, the dean inner shoulder 25 to support a brush back vice being shoWn in locked position.

Fig. 7 is a verproject slightly above the ring in Order that ico tic'al section on the line 7 7 of Fig. 5. Fig. 8 it maybe rigidly held as presently described.

5o is a side elevation of a modified form of the The brush back has perforations 27 to rebox. Fig. 9 is a side 'elevation of the inner ceivo the bristles as shown in Fig. 2.

v receptacle or box proper used in connection Beneath the ring 24 and extending entirely across the box is an abutment plate 28 upon which the ends of the bristles strike when the bristles drop through the perforations in the brush back. The distance between the brush back and abutment plate should be equal to the thickness of the brush back. The reason for this is that the protruding ends of the bristles are covered with a cement then drawn back into the brush back, when the cement fastens them to the brush back, after which a false or finish back is applied.

The ring 24 and abutment plate 28 are adj usted in relation to each other by screws 29 which extend vertically through the ring and plate and rest on the floor of the box, while the heads extend above the ring to the level of the brush back and against the lining and guide 30 tobe more specilcally referred to presently. The lower ends of the screws are of greater pitch than the upper ends, to give the abutment plate 28 a relatively fast movement, thus enabling it to be quickly adjusted to different thicknesses of brush backs and yet leave the screw heads level with the brush back.

After the brush back is placed in the ring 24 the lining or guide 30 is placed in the box. This guide is thick enough to overlap the edge of the brush back and it` also rests on the screws 29 and extends to the cover 14. Consequently when the cover is locked, the guide is clamped firmly in place and prevents the displacementof the parts belowit. Some such arrangement as this is essential to hold `the parts in place, as the box is subjected to violent concussions.

The lining 30 tapers downward and its inner wall is vertically corrugated to prevent the bristles from tipping over when in contact with it. The taper of the guide serves to assemble the bristles in a compact mass on the brush back, so that when the box is shaken the bristles readily enter the holes in the brush back. On the sides ofthe box are perforated lugs 21 which serve as guides and which are adapted to run on guie posts on which the box is held when it is shaken.

In Figs 8 to 12 I haveshown a slightly modified form of box, which has the cover integral the main shell of the box and is therefore with rather stronger than the box shown in Figs. 1 to 7.

The modied form of box l0 has an outer shell 32 which is open at the ends only, while the inner box comprises the flaring top portion 33, and vertical base portion 34 and is substantially like the box 10 with its cover removed. The box 33, 34 has the same internal arrangement as the box 10, see Fig. 10, and it is slipped endwise into the shell 32 which has the guide lugs 31, so that when the inner box is in place the whole device can be readily shaken up and down.

Any suitable means may be employed to lock the box to the shell, a convenient and secure device being illustrated, which has notches 35 in the top edge and opposite sides of the inner box adapted to engage ecoentrics or cams 36 carried by shafts 37 which are journaled in the outer shell. The eccentrics turn in slots 38 in the top of the shell 32. 'lhe outer ends of the shafts have handles 39 by whichtheshafts can be turned and the ec'- centrics moved into or out of engagement with the notches 35.

When either form of box is to be used, the brush back is adjusted in the ring 24, the lining and guide 30 inserted above the ring and brush back, the box filled with bristles placed endwise to the brush back, and the parts held in place by fastening the cover to the box; in the modified forrnthe top of the shell 32 serving as a cover. .The box is then jolted up and down, being preferably held on guide posts extending through the lugs 31, and the bristles drop through the holes in the brush back with their lower ends resting on the abutment plate 28.

u By using aseries of rings 24 and linings or -guides 30, ot' varying internal diameters, one

box may be used for Vmany sizes of brushes, thus obviating the necessity of using the customary large number of boxes and thereby making a substantial saving inthe cost of an outfit for making brushes.

I know that it is not new to form a box with an inclinedor tapering top, a brush back .brush back holding ring, the abutment plate securedgto the ring and held beneath it, a tapering guide above the ring, and a cover for the box, substantially as described.

3. The combination with the box, of the brush back holding ring, the abutment plate adjustably secured to the under side of the holding ring, the tapering guide to rest above a brush back and extend to the top edge of the box, and a cover to rest on the guide and lock the parts in the box, substantially as described.

4. The combination of the box having a closed bottom and atop closure, of the brush back holding ring, the abutment plate, the adjusting screws extending through the brush back holder and abutment plate and resting on the box bottom, and the guide between the brush back holding ring and box top, substantially as described.
